The specific weight, also known as the unit weight (symbol γ, the Greek letter gamma), is a volume-specific quantity defined as the weight W divided by the volume V of a material: = / Equivalently, it may also be formulated as the product of density, ρ, and gravity acceleration, g: = Its unit of measurement in the International System of Units (SI) is newton per cubic metre (N/m 3), with ...
The IEEE symbol for the cubic foot per second is ft 3 /s. [1] The following other abbreviations are also sometimes used: ft 3 /sec; cu ft/s; cfs or CFS; cusec; second-feet; The flow or discharge of rivers, i.e., the volume of water passing a location per unit of time, is commonly expressed in units of cubic feet per second or cubic metres per second.

Water scarcity is also caused by production of water intensive products. For example, cotton: 1 kg of cotton—equivalent of a pair of jeans—requires 10.9 cubic metres (380 cu ft) water to produce. While cotton accounts for 2.4% of world water use, the water is consumed in regions that are already at a risk of water shortage.
At 101.325 kPa (abs) and 15 °C (59 °F), air has a density of approximately 1.225 kg/m 3 (0.0765 lb/cu ft), which is about 1 ⁄ 800 that of water, according to the International Standard Atmosphere (ISA). [citation needed] Pure liquid water is 1,000 kg/m 3 (62 lb/cu ft).
TF – tropical fresh water; F – fresh water; T – tropical seawater; S – summer temperate seawater; W – winter temperate seawater; WNA – winter North Atlantic; For the purposes of load line marks, freshwater is considered to have a density of 1,000 kg/m 3 (62 lb/cu ft) and typical seawater 1,025 kg/m 3 (64 lb/cu ft).
